Description
The application is the divisional application of Chinese patent application CN201380058413.9
Technical field
The present invention relates to for then in extruded type 3D printer, such as (melting-deposition-molding printing of FDM printers
Machine) in printing apply coated long filament novel processing step.Long filament is coated with simultaneously in the external separate processes of printer herein
It can also be used for the appropriate of the prior art and printer be not transformed.The invention further relates to for carry out the method apparatus for coating and
Roller with coated long filament.
Background technology
Rapid prototyping is molded or quickly the preparation method is intended to available three-dimensional CAD data is direct and is rapidly converted into work
Part, and as far as possible without manual intervention or without using mold preparation method.
There are various methods at present in the range of the rapid prototyping method of forming.These can be divided into two classes：Method based on laser
With the method without using laser.
It is stereolithography (SLA) that most widely known laser class, which is simultaneously simultaneously most ancient 3D printing method,.This
In method, the liquid composition of radiation-curable polymer is successively hardened using laser.Those skilled in the art can understand
Find out, manufactured workpiece can only be coloured then on the surface by this method.This is complicated and takes.
Similarly selective laser sintering process (SLS), wherein similarly with SLA, by laser successively selective sintering
Powdery starting material, such as thermoplastic or sinterable metal.It also can only be obtained in first method step in this way
Obtain the 3D objects of monochromatic or nonspecific coloring.This is equally applicable to the third laser class method, " Laminated Object preparation ", wherein will
The layer of paper web or plastic foil with adhesive is with the mutual gluing of layer and by laser cutting.Such as it is retouched in US 6,713,125
Stated object with after stain.
The known 3D printing method that can also be used for preparing polychrome object is UV ink-jet methods.In this three-phase approach, with thin layer
Apply dusty material, UV curable liquids is printed onto in the form of the equivalent layer of follow-up three-dimensional objects on the layer, finally
The layer through printing is set to harden using the sources UV.These method and steps successively repeat.
In EP 1 475 220, prepare the liquid containing curing agent of various different colorings, in WO 2008/077850
Additionally directly mixed before printing process in cell.It is therefore possible to selective colorings.But due to the mixing chamber, clearly
Clear color transition is impossible.In addition, such method is unintelligible in solidification boundary, this can cause relatively low smooth
Spotty staining is simultaneously caused sometimes in the surface of degree.In WO 01/26023, the curing agent group with various different colours is described
Two print heads for closing object, lead to the object part for the elastic property for having different.But the face more than two kinds is not described
Color.
WO 2008/075450 describes a kind of variant, wherein replace being hardened using ultraviolet light using heat radiation, and
Equally use the curing agent composition of various different colours.
GB 2419679 discloses alternative polymer particles for applying various different colorings and hard under various wavelength
The method of change.This method is extremely complex and also results in unsharp color image.
In the method similar to 3D ink jet printings according to WO 2009/139395, successively applies colored liquid and select
It is printed with second liquid to property, causes to be cured with the first liquid and react.Such method can only successively construct oil
Ink, other than it may be mixed between uncured liquid level.
Another method is three dimensional printing (TDP).In this approach, be similar to ink-jet method, by dusty material (but its
It is preferably ceramic) successively selectively it is impregnated with a kind of melt of thermoplastic polymer.After each printing layer, it is necessary to apply new powder
Powder material layer.Three-dimension object is formed when thermoplastic hardening.
In method described in US 2004/0251574, selectively printed with ink after printed thermoplastic plastics.
The advantages of this method is to print highly selectively.But the shortcomings that this method be can not be achieved uniformly and
Bright color image, because ink uniformly penetrating can not possibly be made to the composite material made of (ceramics) powder and binder
In.
In method described in EP 1 491 322, two different materials are printed.The first include binder and
With the colorant for precipitating when second of material and thus selectively colouring on surface.It by this method can be on a surface of an
Generate better color property.But the uniform mixing of both materials and complicated two-phase method become problem.Do not describe
How and whether may insure to realize good color image under polychrome printing.
In US 6,401,002, the various liquid containing different colorant and binder are used.The liquid is separately added dropwise
Or merge via the pipeline in nozzle before dropwise addition process.Those skilled in the art will know that it is not most that both programs, which result in,
Good color image.In the former, the mixing of colorant occurs in viscous liquid on the surface.Therefore this mixing is very
It is complete less.In second of program, the pressure difference in pipeline may cause very strong color change.
Most saved in terms of preparing three-dimension object by print process material and the also best side for Machine Design
Method is melting-deposition-molding (FDM).This is related to extruded type number preparation system.Substantially similar side with slight change
Method, such as also with term：Fuse prepares (FFM), melting extrusion prepares (MEM) or selective deposition molding (SDM) is mentioned.
In FDM methods, two different polymer filaments are melted in nozzle and are selectively printed.A kind of material is
Only then the position of the outer outstanding part (it must be supported in printing operation) of printing such as 3D objects needs on it
The backing material wanted.Then can for example the backing material be removed in acid, alkali or water by being dissolved in.Another material (construction
Material) form real 3D objects.Here, generally also successively realizing printing.FDM methods are described for the first time in US 5,121,329.
Coloring is loosely mentioned in US 2000/20111707, but is not described in.
In method described in EP 1 558 440, each layer of colored printing in subsequent method step.This method is slow
Slowly, and in the printing of cured thermoplastic cause the color image of resolution ratio difference.
In the colored 3D printing method according to US 6,165,406, individual nozzle is used to each color.But therefore
Only very limited colour mixture possibility, and color image becomes very simple.
In US 7, in the variant of the FDM described in 648,664, the building material of various different colorings makes in granular form
Be separated from each other melting, and is mixed with each other by the extruder of centre connection depending on color before being printed application.
This method needs extremely complex device and loses many advantages of FDM.
In the very similar system according to EP 1 432 566, passed through before melt granules are applied by directly printing
The mixing of melt granules is directly carried out in the print head of heating.The mixing can not possibly carry out completely certainly, and print image
Quality is correspondingly poor.Other disadvantage herein also resides in, it is necessary to using particle or powder and these must divide in this machine
Open storage and melting.
US 6,129,872 describes building material and is melted in nozzle and in nozzle end by various coloring agent mixtures
Selectivity is metered into the method in melt.But this leads to undermixing and sordid color image.
US 2010/0327479 describes a kind of method, wherein merging multiple coloured yarns in micro- extruder and at it
In continuously squeeze out to generate new coloring long filament, then its be further guided into print head with print apply.This method needs
It is required that very high and complicated device.Achievable color gamut is also limited by long filament number.In alternative embodiment,
The long filament of different colours can be sent directly into print head and mixed herein.But this variant also shows the disadvantage.
The method of all prior arts, which all only discloses, is wherein based on extruded type 3D printing, otherwise such as FDM 3D printings-
Or the colored technology of the matrix itself of coating material online.But online the shortcomings that being coated with is to need to have accordingly thus
Online coating system special 3D printer.On the contrary, through coloring or basis material containing additive have must use need not
The shortcomings that a large amount of dyestuffs in strategic point, pigment or additive are to realize good result.
